6. Bound by long-range interactions: Molecular crystals and benzene on Cu(111)
Abstract : This thesis investigates molecular systems bound by long-range interactions. Westudy molecular crystals held together by van der Waals forces and the physisorption of benzene (Bz) on Cu(111). READ MORE

7. A study of finite-size, non-perturbative and anisotropic effects on the Lifshitz-van der Waals forces and torque with material dielectric responses from first-principles calculations
Abstract : The van der Waals and the Casimir-Lifshitz forces are forces of attraction that exist between neutral polarizable bodies due to quantum fluctuations. They can be repulsive depending on the material properties and the geometry of the system. READ MORE

8. Microscopic Theory of Exciton Dynamics in Two-Dimensional Materials
Abstract : Transition Metal Dichalcogenides (TMDs) present a giant leap forward towards the realization of nanometer-sized quantum devices. As a direct consequence of their truly two-dimensional character, TMDs exhibit a strong Coulomb-interaction, leading to the formation of stable electron-hole pairs, so-called excitons. READ MORE

9. Colloidal interactions obtained from total internal reflection microscopy measurements and scattering data
Abstract : The scattering of radiation can be used to extract information about the interactions between colloidal (10^{-7}-10^{-3} cm radius) particles suspended in liquids. As colloidal interactions incorporate entropic effects they are weak and while system specific they are governed by a number of general mechanisms. READ MORE
